Answers

Answer 1

Answer:

Answer:

The correct answer is D. 56.4

Step-by-step explanation:

1. Let's review the information given to us for solving the question:

Kilometers hiked by Jason on Saturday = 15.6

Kilometers hiked by Jason on Sunday = 18.1

Kilometers hiked by Jason on Monday = 22.7

2. How many kilometers did he hike during the three days?

Total of kilometers hiked by Jason = Kilometers hiked by Jason on Saturday + Kilometers hiked by Jason on Sunday + Kilometers hiked by Jason on Monday

Total of kilometers hiked by Jason = 15.6 + 18.1 + 22.7

Total of kilometers hiked by Jason = 56.4

Variable y varies directly with variable x, and y = 48 when x = 8. What is the value of y when x = 4?

y =

Answers

y/x=k 48/8=6=k k is the constant y/4=6 y=24

Final answer:

To find the value of y when x = 4 in a direct variation equation, we first solve for the constant of variation, k. Once we have k, we can substitute x = 4 into the equation and solve for y.

Explanation:

To find the value of y when x = 4, we can use the formula for direct variation:

y = kx

where k is the constant of variation. We can solve for k using the given information:

When x = 8, y = 48. Plugging these values into the formula, we get:

48 = k * 8

Solving for k, we find that k = 6.

Now we can use k to find the value of y when x = 4:

y = 6 * 4

y = 24
